Re: Mario's class IV 445nm Kryton + projector pics

Not unless he bought the tail caps and cut them open for the switch, which would get costly as well.

He only needs the swicth? Hmm...that's harder to find. Other than those all I could find were 15A light swicth style switches, and they had a huge housing with em and such. Kinda nasty lookin.

Not only that but the melted plastic fumes may sit on your diode window.

I talked to AixiZ last night--

the acrylic lens would be toast in no time--

He said the 405nm AixiZ glass will be fine for the 445nm- PM me if anyone wants a blank module(with stock lens , a AixiZ glass 405 lens and a bare w/ ribbon 445nm diode w/ stock lens for 65$ shipped to USA--starting a list to see if I want to do this. Need 10 more 'wanters'--Hak

Digi-Key - 559PB-ND (Manufacturer - 40-4681-00)

That could possibly be made to work, could it not?

Or perhaps this, which would need a lot more work

Re: 445nm "sled" pics

This has to be the most epic event in the history of the hobby!

I've been thinking about that ever since.

On laserchat I'd never shut up about blue lasers. The wish has be granted man

Heh this all has to go into the end cap of my Kryton - basically we need to find heavier duty versions of the DX switches I was using - DealExtreme: $1.94 Clicky Switch for Flashlights (16mm 5-Pack)

It says they're rated for 1.5A but it's obvious they can't handle it

Re: Mario's class IV 445nm Kryton + projector pics

Well, some 9-LED flashlight are a few quarters more than that, it might be worth just buying bulk flashlights and taking them apart. But I'll keep looking.

Re: Mario's class IV 445nm Kryton + projector pics

Ok, electronics help please Refer to diagram below.

Ok, so the driver supplies 750mA to the diode, as denoted in the diagram. I'm guessing X would = around 1.5A (Depending on the battery voltage, I would assume the closer to the diode's Vf the battery is, the less current the driver will draw from the battery since it needs less boosting)? Assuming that this is case negative, how much current would then pass through the clicky switch? :thinking::thinking::thinking:

Re: Mario's class IV 445nm Kryton + projector pics

Mariomaster said it was about 1.5amps going through the clicky switch on his build.

Yeah, but how does he have it configured? It it's case -, then I don't understand how 1.5A would make it to the switch since current comes from the + part of the battery, flows into the driver, driver spits out 750mA. Then flows back into the negative pole of the battery. Perhaps I'm over thinking?

Re: Mario's class IV 445nm Kryton + projector pics

You'd have to ask him about that. I really don't know anything when it comes to electricity. I really wish they would have taught us that in highschool...

 

[MarioMaster]

Re: Mario's class IV 445nm Kryton + projector pics

Electricity flows in a circular path - so where there is 1.5 amps flowing through X, there must also be 1.5 amps traveling through the clicky switch.

The host acts as the negative wire from the battery to the driver.

I thought the host acted as a negative wire to the diode though. The host never touches the driver. In order for the 1.5A to reach the switch in the diagram, wouldn't those 1.5A also have to navigate through the diode?

Re: Mario's class IV 445nm Kryton + projector pics

The driver gets its negative voltage supply though the case pin of the diode (which is isolated for these diodes) which then gets shorted to the negative of the driver.

So current flows from the + of the battery, through the driver, through the diode, out the case pin, through the host, through the clicky, and then back to the battery

Exactly...and only 750mA should be flowing through the diode, correct?

This is fine for V5 FlexDrives (that is, if your talking about going from the diode case, to the driver negative output), but remember that if you use the new Micro Boost driver, not to let the diode case (negaitve), go to to the driver output like you can do with FlexDrives...

Because with FlexDrives, both input and output negatives on the driver are continuous. (one and the same)

But this is not the case with a Micro Boost...

(just to warn those why didn't realize that)
